TechdryAd Mortar Additive

TechdryAd Mortar Additive is a water repellent admixture for cement/sand mortars. Adding it to the mortar mix makes the mortar water resistant and reduces the efflorescence to the mortar. It also improves the adhesion of the mortar to the water repellent blocks (Tech-Dry® Blocks) and improves the workability of the mortar mix.

The mortar mix is recommended as a water repellent admixture for cement/sand mortar designed specifically for laying water repellent concrete blocks (Tech-Dry® Blocks) made with the addition of Tech-Dry® Block Emulsion.

It may also be used as a water resistant admixture for other cement/sand mixtures such as cement/sand renders or concrete masonry.

Please read the product information for the correct application and safe handling before use. For laying water repellent blocks (or Tech-Dry® Blocks), we recommend to use 1.0 litre of Techdryad Mortar Additive per 40kg of cement at a cement/sand ratio of 1 to 4. The maximum cement/sand ratio should not exceed 1 part cement to 5 parts sand.
